The invention relates to a balancing shaft for a multi-cylinder engine having at least one unbalanced weight portion (21, 22; 23, 24) and at least one bearing (16, 17), the at least one unbalanced weight portion (21, 22; 23, 24) being associated with the bearing (16, 17) and the bearing (16, 17) has a radial running face (18) which extends only partially over a periphery of the bearing (16, 17) and a centrifugal force which results during rotation of the balancing shaft (11) is situated within a region of the bearing (16, 17) that is formed by the running face (18) which extends partially over the periphery of the bearing (16, 17), wherein a running ring segment (51) is associated with the partially formed running face (18), said running ring segment adjoining the partially formed running face (18) of the bearing (16, 17) and forming, together with said partially formed running face (18), a completely closed running face (20) of the bearing (16, 17) and having at least one lateral edge (54) which delimits the width of the running ring segment (51) and which spans the partially formed running face (18) and is provided in an unsupported manner.
A balancing shaft for a single-cylinder or multi-cylinder engine having at least one unbalanced weight portion and at least one bearing, the at least one unbalanced weight portion being associated with the bearing and the bearing has a radial running face which extends only partially over a periphery of the bearing and a centrifugal force which results during rotation of the balancing shaft is situated within a region of the bearing that is formed by the running face which extends partially over the periphery of the bearing, wherein a running ring segment is associated with the partially formed running face, said running ring segment adjoining the partially formed running face of the bearing and forming, together with said partially formed running face, a completely closed running face of the bearing and having at least one lateral edge which delimits the width of the running ring segment and which spans the partially formed running face and is provided in an unsupported manner.
The balancing shaft as claimed in claimed 18, wherein the unbalanced weight portion is provided at an outer end of a basic element.
